WR110 Series Compact Water Pressure Regulator

Brand: OLH by Richge Technology (睿其格科技) 

Product Positioning

     WR110 series is a direct-acting compact pressure regulator exclusively developed for industrial cooling water and process water pipelines. Constructed with anti-corrosion special brass housing, this valve delivers steady water pressure regulation and diverse installation options to match miniature water circulation systems.

Structure & Working Principle

     --Direct-acting composite piston-diaphragm structure with built-in relief function

     --Applicable medium: Tap water and general industrial water; not suitable for deionized or ultra-pure water

     --Valve body adopts special brass material with anti-rust and anti-scaling performance

     --Equipped with top-mounted lockable blue adjustment knob

     --Reserved Rc1/8 side port for pressure gauge installation

     --Two mounting solutions: direct threaded installation or optional B21-1P fixing bracket

Core Key Features

1. Two Optional Adjustable Pressure Ranges

     --WR110-X224 low-pressure version: 0.08–0.39 MPa

     --WR110-X215 medium-pressure version: 0.05–0.69 MPa Max working pressure reaches 0.8 MPa, and the proof pressure stands at 1.72 MPa.

2. Water-Grade Anti-Corrosion Brass Construction

     Special brass body effectively resists water corrosion and limescale accumulation. Matched with water-resistant rubber seals, the operating temperature covers -5℃ ~ +60℃.

3. Mini Compact & Lightweight Outline

     Overall dimension φ45×75mm with net weight only 0.26kg, perfectly fitting embedded equipment and narrow cooling water pipelines.

4. Stable Regulation with Overpressure Relief Protection

     Fast response and tiny output pressure fluctuation. The internal relief channel automatically releases excess pressure to safeguard downstream pipelines. The lockable knob avoids unintended pressure adjustment caused by vibration or accidental touch.

5. Flexible Thread Ports & Multi-Directional Mounting

     Standard Rc1/8 and Rc1/4 ports; NPT thread optional for X215 model. A dedicated side gauge port is reserved, and vertical installation is recommended for optimal performance.
